Did it have any oil pressure?

Yes 70 psi warm under throttle 30-40 idle when the engines were in the diner boat they only had 55 under throttle, and 11lb bypasses, if I didn't add pressure and 30 lb bypasses I would have smoked them instantly...

These were built by the biggest hack I ever seen, if I had been the guy that paid for them and found this I would be in jail!

Addressing:
Fuel flow
Oil flow and cooling
water flow (volume and psi if non stock Merc)
Electrical - yes. electrical. Wanna know how many Cannon plugs, grounds (watch that new paint !), and variety electrical gremlins get created when replacing/rebuilding a motor.

As far as to read up on all this - there is much here but not at all organized. Best way to find them first is by finding motor broken or tuning problem threads. A lot of answers/questions given/asked by fellow members will be rigging related.

#1 thing to do - if you have a question, ask it ! No one will schit on you for asking. You will be schit on for not listening to advice and for not having some diagnostics of the problem at hand.

Like the famous: "My boat just died. What is it ?" kind of thread. Some things need to be chacked and some symptoms leading up to this, if any, should be shared with the question.

Overall, if you show you care, others will care with you.

That thing is a mess!!!!!!

Yaaaa unreal!!

What does the crank journal look like?

Do my eyes deceive me, or does it look like someone took an angle grinder to the crank?
